Before we start the movie we see a tiny black Bdellovibrio predatory bacterial cell inside a bigger fluorescently labelled prey E.coli cell. The Bdellovibrio has invaded this cell and as we start the movie, we see the Bdellovibrio elongate bidirectionally, growing and using the insides of the prey cell. Then it septates unusually to give 5 progeny cells, and the E.coli goes dark as those progeny cells lines it and escape and go on to attack more prey bacteria.
